Consider again the civilization described in the previous question. (They live on a planet orbiting 10 AU from a close binary star system that consists of a 15 MSun red giant star and a 10 MSun black hole surrounded by an accretion disk.) Through a bizarre (and scientifically unexplainable) fluctuation in the space-time continuum, a copy of a book from that civilization arrives on your desk; it is entitled Iguoonos: How We Evolved. In the first chapter, you learn that these beings evolved from organisms that lived 5 billion years ago. Which of the following statements should you expect to find as you continue to read this book?
A. Their immediate ancestors were chimpanzees.
B. As a result of traumatic experiences to their evolutionary ancestors, they dislike television.
C. They evolved on a different planet in a different star system, and moved to their current location.
D. They evolved from primitive wormlike creatures that had 13 legs, 4 eyes, and bald heads, thus explaining why such critters are now considered a spectacular delicacy.
E. They believe that the presence of two stars in their system was critical to their evolution.

How objects on Earth are affected by gravitational force.

Answers

Answer:

The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it

A fisherman sees 7 wave crests go by in 10.0 s. The crests are 2.43 m apart. Find the frequency of the wave. (Unit = Hz)​

Answers

Answer: 0.7

Explanation:

A fisherman sees 7 wave crests go by in 10 s, with wavelength (λ) ia 2.43 m has the frequency of the wave is 0.7 hertz.

What is a wave?

A wave is defined as the propagation of distrubance from one place to another. It can carries energy when it propagates into the medium without the net movement of the particles.

It refers to the variations or flow of energy without the transfer of mass of particles or matter. The waves can be visible or invisible. Light and sound are travel in the form of waves.

In waves, the wavelength, frequency, wavespeed and time period can be identified. Frequency refers to the number of oscillations takes place per unit time. It is measured in hertz (Hz).

Wavelength(λ) defines the distance travelled by the wave in a particular time in one vibration. It is also defined as the spatial period of the wave. It can be obtained by taking ratio between wavespeed and frequency. The unit of wavelenght is meter(m).

Wavespeed of the wave equals the wavelength and frequency. It defines the distance travelled/ number of meter covered by given time. Wavespeed (v) = wavelength (λ) / frequency (f). Its unit is m/s.

Time period is inversely proportional to the frequency (f). The time taken by the wave to complete its one oscillation is called time period. Time period = 1 / f . Its unit is seconds (s).

From the given,

time = 10 secs

no of waves = 7

wavelength = 2.43 m

To obtain frequency from the givens, the formula for frequency is:

frequency = no.of.cycles of waves / time taken

                 = 7 / 10

          f     = 0.7 hertz.

Hence, the frequency of the wave is 0.7 Hz for 7 waves and given time 10 s.

If the current in a wire which is placed perpendicular to a magnetic field increases the force on the wire

Answers

Answer:

The force on the wire increases

Explanation:

Since the force on the wire F = BILsinФ where B = magnetic field strength, I = current in wire, L= length of wire and Ф = angle between the magnetic field and the wire.

Given that the magnetic field and the wire are perpendicular, Ф = 90°

So, F = BILsin90° = BIL

Since B and L are constant, F ∝ I

So, if the current in the wire increases, the force on the wire also increases.

You are rolling a ball in a veiled by kicking it. You get tired and stop kicking the ball. What happens to the potential energy of the ball.

Answers

Answer:

The potential energy of the ball becomes 0

Explanation:

When kicking the ball, and it moves up, the potential energy of the ball increases. When the ball descends downwards, the potential energy of the ball reduces.

This is so because potential energy increases as height increases and decreases when there is a reduction in height.

So, when you stop kicking the ball and you place the ball on the floor, the ball becomes static (motionless); hence, the potential energy becomes 0.

Two particles are placed near each other. Each has a charge of +2e. One particle exerts both an electric force Fe and a gravitational force Fg on the other particle.

Answers

Answer:

hi your question is incomplete below is the missing part of your question

Question : How does the direction and magnitude of Fe compare to Fg

answer : Not enough information is given

Explanation:

From the above information given in the question the direction and magnitude of FE cannot be compared to Fg and this is simply because the mass of the particle that  force is been exerted on is not given therefore we cannot ascertain the magnitude of the gravitational force. Therefore we can conclude that not enough information is given

Imani stirs a cup of hot sencha tea with a cool silver spoon. She notices that the silver spoon becomes warmer. What energy change occurs when the silver spoon is added to the hot cup of sencha tea?

A. The spoon adds its cold to the hot tea

B. The hot tea absorbs the heat from the spoon

C. The cool spoon causes the water to expand thus cooling it

D. The tea loses heat to the spoon causing the spoon to become warmer

Answers

Answer:

D. The tea loses heat to the spoon causing the spoon to become warmer

Explanation:

When the silver spoon at a lower temperature than the tea, is added to the tea, it makes thermal contact. Hence, the heat transfer starts between the two until the equilibrium is reached. We know that the heat transfer takes place from the body with a higher temperature to a body with a lower temperature. As a result, the body with higher temperature loses heat and its temperature lowers down. While the body with a lower temperature gains heat and its temperature rises.

Therefore, the correct option is:

D. The tea loses heat to the spoon causing the spoon to become warmer

This is vety hard this is level 4 number 10 on code.org plsss help me

Answers

Answer:

Explanation:

Coding is all about logic, since I do not have the actual problem from the website I will guide you on how to solve this.

Since you need to go a certain direction you will need to indicate to the character which direction to go. Next, we need to prevent the player from travelling through a wall, we can accomplish this using an IF/ELSE statement. IF the next block in that direction is a wall then do not move forward, ELSE move forward. We would call this statement every time the player tries to move in any direction. Finally, once we reach the lettuce we need to continue picking it until there is no more. To do this we use a While loop, that checks to see if there is any more lettuce, if there is it will run the code to pick up lettuce, if there is NO more then the While loop will exit. That would be the entire code.

Please help! What's the answer to this question, A 5.6 nC electric charge is placed in an Electric Field and experiences a force of 7.4 μN. What is the magnitude of the Electric Field at that location?

Answers

Answer:

1321 N/C

Explanation:

From the question,

Electric Field (E) = Electric Force(F)/Electric Charge(q)

E = F/q............ Equation 1

Given: F = 7.4 μN = 7.4×10⁻⁶ N, q = 5.6 nC = 5.6×10⁻⁹ C

Substitute these value into equation 1

E = ( 7.4×10⁻⁶)/(5.6×10⁻⁹)

E = 1.321×10³ N/C

E = 1321 N/C

Hence the magnitude of the electric field at that location is 1321 N/C

the soft ballplayer does 9876 joules of work when hitting a ball into center field. Assuming the ball landed 100 meters away from home plate, how much force did the player use to hit the ball?

Answers

Answer:

F = 987600 N

Explanation:

Force Equation

F=ma

Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration. We use Newtons, kilograms, and meters per second squared as our default units, although any appropriate units for mass (grams, ounces, etc.) or velocity (miles per hour per second, millimeters per second2, etc.) could certainly be used as well - the calculation is the same regardless.

Solve

F = m * a

F = 100 kg * 9876 m/s2

F = 987600 N

Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

During a testing process, a worker in a factory mounts a bicycle wheel on a stationary stand and applies a tangential resistive force of 130 N to the tire's rim. The mass of the wheel is 1.70 kg and, for the purpose of this problem, assume that all of this mass is concentrated on the outside radius of the wheel. The diameter of the wheel is 50.0 cm. A chain passes over a sprocket that has a diameter of 8.75 cm. In order for the wheel to have an angular acceleration of 3.50 rad/s2, what force, in Newtons, must be applied to the chain

Answers

Answer:

The force that must be applied to the chain in order for the chain to have the given acceleration is approximately 694.2 N

Explanation:

The given restive force, [tex]F_f[/tex] = 130 N

The mass of the wheel, m = 1.70 kg

The diameter of the wheel, D = 50.0 cm

∴ The radius of the wheel, R = 50.0 cm/2 = 25.0 cm = 0.25 m

The diameter of the sprocket over which the chain passes, d = 8.75 cm

The radius of the sprocket over which the chain passes, r = 8.75 cm/2 = 4.375 cm = 0.04375 m

The angular acceleration, α = 3.50 rad/s²

Torque, τ = I·α

Where;

I = The moment of inertia = m·R²·α

The net torque = The applied torque - The friction torque

Therefore, we get;

I × α = m × R² × α = F × r - [tex]F_f[/tex] × R

1.70 kg × (0.25 m)² × 3.50 rad/s² = F × 0.04375 m - 120 N × 0.25 m

F = (1.70 kg × (0.25 m)² × 3.50 rad/s² +  120 N × 0.25 m)/(0.04375 m) = 694.214286 N

The force that must be applied to the chain in order for the chain to have the given acceleration, F ≈ 694.2 N
